If you've ever been to the Blarney Stone in Ireland, bent over backwards, and planted a big, wet kiss on it, congratulations! You practically just tongue-kissed every man, woman and child in the city of Miami!

The Stone, which is probably kissed by around 400,000 people yearly, has been named the world's most unhygienic tourist attraction by researchers, who admit they have no evidence to back up their claims. Hmmmm ... how scientific. The same folks also think that the gum wall in Seattle, which is (surprise!) a wall people stick their gum on is the second dirtiest, followed by Oscar Wilde's grave (that's a little more believable). Apparently, old human slobber is more unhygienic than bird poo, since St. Marks Square, in Venice, which is pretty much plastered with bird crap, is only number four.

So remember, when you kiss that rock trying to get "the gift of gab," you might actually be getting "the gift of cold sores."
